Sorry this is long.
11 years ago my grandmother died, her house was owned by her and my DF and her wishes were that her house would be left to me and my brother. Brother had no interest in the house at all so I moved in there with my now DH. House was signed over to me and DF decided on a set amount which I gave brother for his share of the house. Said that we had drawn a line under it, it was ours to do with what we liked. It was a shell of house worth very little in a poor area and we spent a lot of money on completely renovating it to make it habitable.
Now we have 2 DC and need more space. Concerned about going to school in rough area with terrible air quality (kids have allergies). Spoke with DF and he was supportive. Now we've had the house valued and suddenly he's said it's 'unfair' that were 'making money' out of the property (we're just moving to a nicer area for the sake of our kids FFS).
He said that when he dies now his property (which in his will was going to my brother on the previous 'understanding' it would be split 50/50) would now be split so that my brother would get the majority as half of any "profit" made between the price we'd agreed years ago and the amount we sell it for would be deducted from my inheritance.
He doesn't care that we haven't actually made any money because we've spent so much on it. Doesn't care that we have made a home here for 11 years but have genuinely outgrown it.
He doesn't care that by the time this happens my kids will be growing up/potentially going to uni/looking for their own houses and could use the help (brother doesn't have kids). Doesn't care that he's effectively gone back on his word saying that the house was ours because years later he is punishing us for wanting to move.
Brother has had the money for years and decided to stay living at home with DM. My view is he could have put it towards a house/bought a cheap house like ours and gone to the trouble of doing it up, etc. and chosen not to. It's not my fault so why am I and my children being punished?
Just to say I know I'm lucky to have any kind of inheritance. But its the principle of this. And it hurts that DF is seemingly punishing us (including my kids) for wanting to do what's best for DC. Particularly when he's always said he supports us moving.
